在Java中执行后关闭批处理文件

Question

I am trying to create a bat file and running it. Once execution is complete, bat file should close.

String cmd = "cmd /c start" + " "+"java -jar batchfilepath"+" "+"\n exit";

Runtime r = Runtime.getRuntime();
Process pr = r.exec(cmd);

Issue- I am able to close the bat file but it closes before execution completes.

I tried following ways

1.if(p.waitfor()==0)
{rt.exec("taskkill /IM cmd.exe");}
2.cmd /c start \wait  
3.cmd /k start \wait 
4.processBuilder

Help me on this.

Answer 1

add /wait to wait for the entire execution to complete and then close the batch file.

Try this. Hope this works

cmd /c start" + " "+"/wait"+"

Answer 2

This worked for me with a java.jar file in windows.

The batch file:

@echo off
cd  C:\NetbeansProject\
java -jar MP2ways.jar

End of the program after data displayed, added:

   System.out.println("\n Hit Return to exit... ");
   String kS = scan.nextLine();
   System.exit(0);

Window closes when hitting return. (for what it's worth, which ain't much``)
